Sigiriya is a must visit for every Sri Lankan (Rs. 50) and most tourists (Rs. 3,000). The natural rock column has been inhabited by humans (as a monastery, mainly) since the 3rd Century BC, but its most famous inhabitant was King Kashyapa in 477 AD. We’ll get to all that later. Sigiriya is 60-90 minute climb but you can spend a lot longer there. The terraced top has beautiful views and it’s a great pleasure to imagine all the ancients who hung out there.
